With the development of economy in China, city orbit traffic develops quickly. City track traffic in city operation, so the operation will inevitably destroy the environment, affect the lives of the residents. In order to solve this problem, in city rail traffic has taken measures for vibration. In recent years, the steel spring vibration isolation in domestic city subway construction until the widespread application. The traditional vibration technique in vibration and noise reduction for the damping effect is limited, train running through the vibration and noise will affect people's life and health, to the surrounding environment to a certain extent, also caused adverse effects, so the vibration in the high requirements of special section of traditional damping technology has apparently no longer apply. Emerging steel spring shock absorber has obvious effect, small repair workload characteristics. The first Metro Line 13 in Beijing, Guangzhou and other applications, Shanghai city have also subsequently used a steel spring vibration damping technology.
